反井钻机在斜井施工中的应用

Application of Converse Drilling Rig to the Construction of Inclined Wells

通过工程实践,将反井钻机施工技术成功应用到48°和60°斜井开挖施工中,证明反井钻机施工斜井工艺完全可以替代传统的人工反导井或爬罐斜井施工工艺,是一种高效、安全地施工工艺。同时反井钻机施工斜井多见于60°～90°,反井钻机施工技术在48°斜井的开挖施工中的成功应用,将反井钻机的应用范围扩大到48°～90°。

Through engineering practice, the converse-well drilling rig construction technology was applied to the inclined shaft excavation with degree of 48° and 60°, it was shown that inclined wells was proved the converse construction process can be replacing the traditional manual converse missile or climbing well for inclined shaft construction technology. It is a highly efficient and safety construction method. At the same time, converse well drilling rig construction was particularly prevalent for the inclined shaft with the degree of 60°-90°, the converse well drilling rig construction technology of shaft excavation with the inclined degree of 48° successfully, shows that it may expand the application the converse drilling wells to the scope of inclined degree of 48°-90°.
